To all wzlom it may concern:

Be it known that we, HERMAN A. PorrnN- ynrosnn and ARTHUR l). STRONG, citizens ot the `United States, residing, respectivel at o Hammond, inthe county of Lake and tate of lndiana, and Chicago, in the county ot @ook and State of Illinois, haveinvented new and useful Improvements in Fire Arches, of which the following is a specilo cation.

rll`his invention relates to tire-arches tor furnaces, and more particularly to drearches kmade of rows of tiles suspended from metal members in thefupper structure or" the l arch.

'20 to prevcntcold air being drawn down into the combustion chamber through the spaces between the tiles. o

Another object of our invention is to have the I-beams which support the tiles suspended from the plates and'to provide sulicient clearance between the parts that the tiles and I-beams may expand and contract laterally relatively to each other nnder the varying temperatures to which the arch is subjected without disturbing the alignment of the plates and their connections With said members noi` cause the tiles to eXertsuch undue pressure against each otheri-on expansion that the tiles `vwill be cracked or lchipped or otherwise be injured under expansion.

A. further object of our invention is to have the plates engage the 'll-beams in 'such manner that the joints between said parts 4@ will at all times be closed to/the downward passage of cold air between them noW matter to what extent the structure expands under the maximum degreeof heat.

The invention consists further in the matters hereinafter described and more particularly set'forth in the appended claims.

. In the .accompanying drawings- Fig. 1 is a longitudinal vertical sectional view taken through a nre-arch constructed 510 in accordance with our invention;

F ig. 2 is an enlarged transverse vertical sectional View taken on line 2-2 ot Fig. l.; F ig. 3 is a longitudinal vertical sectional View taken on lineB-S of Fig. 2;

F 1g. 4 is a perspective viewo-f one ,of the I-beam supporting plates; and

Fig. 5 1s a plan view of av detail of construction to be hereinafter described.

"lhe nre-arch shown in the drawings coinprises a plurality of tiles'l, .l arranged in longitudinal rows extending at an inclination upward and inward from the front wall of the furnace setting, as usual in structures of this general character. As illustrated in Figs. l and 3, the tiles l in each longitudinal row rest against each other along their engaging front and rear faces. The tiles l in adjacent longitudinal rows have substantially sidewise contact with each other, as shown in Fig. 2. ln cross-section, the tiles l are shaped substantially as shown in Fig. 2, thus providing the tiles with interfitting projections and recesses 2, 3, respectively, along their side faces to provide ballies to the passage of heat upward and cold air downward `between the sides of the tiles.

rllhe upperstructure for the arch includes a plurality of vertically arranged metal channel members ll, t located above the tiles l, l and extending transversely across the arch between and supported by the side' walls (not shown) of thev furnace setting. The members d, 4l are spaced apart laterally and .are maintained in that relation by any suitable means. Extending transversely of the members Il, d and below them arey a plurality oi laterally spaced I-beams 5, 5, one for each longitudinal row of tiles l, l, as shown in Fig. 2. Each tile l is provided between its side laces with an upwardly opening recess or groove 6 to receive the lower dange or web 7 of the associated I- beam 5. The recess 6 in each tile is shaped 'as shown in the drawings to provide shoulders 8, 8 to rest on the lower Hange or web 7 of the I-beam 5 between them. rlihis sus-l pends lthe tiles from the I-beams.

'lhe I-beams 5 project above the tops ot the tiles, and for suspending them from Ithe transverse members 4, e, we provide a pluin said'suspending plates.

` the cross-members j tiles.

arch makes the plates 9*f take a like angle.

rality of relatively flat plates 9, 9 having upwardly extending side flanges 10, 10 engaging under the upper flanges or heads 11 of the llbeams 5, as shown. Eachplate 9 is provided with an upwardly projecting rib or web 12 vextending transversely acro it, and said web has elongated bolt holes 13, 13 adjacent the ends thereoi'. These receive bolts 14, 14 for connecting the plates 9 with suspending plates 15, which in turn .are secured to the transverse members 4 by. bolts 16 extending through elongated bolt holes 17 The bolts 14 bolt holes 18 in members 4 and forwardly inclined lower sections to fit against the webs 12.

While we have shown and described herein in detail an archI embodying the features `of our'invention, it is of course to be understood that the details of construction and arrangement of parts' may be variously changed and. modified^l without departing from the spirit and scope of our invention.

We claim as our invention: Y

1. Ar fire-arch, comprising an upper strucin rows beneath the same, I-beams engaged with said tiles and projecting above the same, plates extending between and engaged with said -beams above said tilesfor suspending the ll-beamsfrom said plates, said plates extendingover the joints between said tiles for preventing the downward passage of air between said tiles, means for preventing the passage of air between said plates and -beams, and .means `for suspending said plates vfrom said upper structure.

extend through elongated said plates 15as shown.

By the construction shown and described, the `i12-beams 5, 5 suspend. the tiles 1, 1 from 4 through the plates 9 and 15, respectively.` The plates 9`extending' between the -beams 5, 5 cover the joints between the tiles, not only in each row but'in the adjacent rows, and thus prevent cold air being drawn down into the combustion chamber of the Jfurnace through the spaces between the tiles. Moreover, the upright flanges 10, 10 at the sides of the Xplates 9 engaging under the heads 11, 11 of the -be'ams prevent the downward passage of cold air between such parts. The plates 9,. between the -beams are also arranged'in rows, and each plate has an offset end 19 overlapping the straight endl of the adjacent plate to provide air seals betiveen the meeting ends of the plates, as shown in Figs. 1 and 3,

As shown in Fig. 2, spaces 5 are pro.- -vided between the plates 9 and the -beams 5. This presents the clearance required Jfor the lateral expansion and contraction of vthe `-beams relatively to the plates 9, which are fixed to the cross-members 4 against such movement. By the recesses 6 the tiles 'may expand and contract laterally into and out of sidewise contact with' each other vand the spaces 5 enable movement of the -beams ture, a plurality of contacting tiles arranged under expansion of the tiles, thus relieving in rows beneath the same, lll-beams engaged the latter of undue pressure when in contact with said tiles and projecting above the and avoiding cracking and chipping of the'` same, plates extending between said llbeams,
